After a brief historical presentation of the CODALEMA setup at the Nançay radio observatory, the performances and some of the main scientific results obtained will be presented: the radio detection efficiency, some evidences for a geomagnetic origin of the air shower electric field in the EastWest and NorthSouth polarizations and a preliminary energy calibration. Finally, the future upgrade of the experiment is mentioned. © 2010 Elsevier B.V. Source

An active dipole antenna is in operation since five years at the Nançay radio Observatory (France) in the CODALEMA experiment. A new version of this active antenna has been developed, whose shape gave its name of Butterfly antenna. Compared to the previous version, this new antenna has been designed to be more efficient at low frequencies, which could permit the detection of atmospheric showers at large distances. Despite a size of only 2 m×1 m in each polarization, its sensitivity is excellent in the 3080 MHz bandwidth. Three antennas in dual polarization were installed on the CODALEMA experiment, and four other have been recently installed on the Auger area in the scope of the AERA project. The main characteristics of the Butterfly antenna are detailed with an emphasis on its key features which make it a good candidate for the low frequency radioastronomy and the radio detection of transients induced by high energy cosmic rays. © 2010 ElsevierB.V.Allrightsreserved.

In the ALICE experiment, at forward rapidity (2.5 < y < 4), the production of heavy quarkonium states is measured via their μ+μ - decay channels. We present the first measurement of inclusive J/ψ production, down to pT = 0, from Pb-P-b data collected at the LHC at √sNN =2.76 TeV. Preliminary results on the nuclear modification factor (RAA) and the central to peripheral nuclear modification factor (RCP) show J/ψ suppression with no significant centrality dependence and an integrated . © CERN 2011.

From an adjustment on a recent selected data set of partial α-decay half-lives of 344 ground state to ground state transitions, analytical formulas are proposed for log10T1/2(s) depending or not on the angular momentum of the α particle. In particular, an expression allows to reproduce precisely the partial α-decay half-lives of even-even heavy nuclei and, then, to predict accurately the partial α-decay half-lives of other very heavy elements from the experimental or predicted Qα. Comparisons have been done with other empirical approaches. Moreover, the potential barrier against α-decay or α-capture has been determined within a liquid drop model including a proximity energy term. Simple expressions are provided to calculate the potential barrier radius and height. © 2010 Elsevier B.V. Source

The ALICE Collaboration has measured the inclusive J/ψ production in p-Pb collisions at the nucleon-nucleon center-of-mass energy sNN=5.02TeV. The comparison of the results on the nuclear modification factor as a function of rapidity and transverse momentum with theoretical predictions shows a fair agreement with a shadowing based model and energy loss models with or without a shadowing contribution. The J/ψ production has also been measured by computing the J/ψ nuclear modification factor as a function of the event activity, as well as the yield and mean transverse momentum dependence with the relative charged-particle multiplicity measured at mid-rapidity. © 2014 Elsevier B.V.
